This is a wonderful piece of software, granted, but:
1) It shows as invalid games I can install with other managers (SSBB and Wii Party).
2) Weirdest of all: I could extract all my WBFS partition's games to a NTFS partition except SSBB. It is canceled when the process is finished, the file is deleted from NTFS and it is shown in red letters. I can play the game perfectly, but it won't be extracted to a .wbfs file. I tried the original ISO to try to transform it, but it will show as invalid. CISO (via isotociso) also doesn't work.
